A South Korean entertainment agency behind a 16-year-old singer who triggered a fresh rift between China and Taiwan by holding a Taiwan flag said Monday it did not force her to apologize.

Chou Tzuyu, the only Taiwanese member of South Korean K-pop girl band Twice, inadvertently shot to the top of Taiwan's election agenda over the weekend.

In a video released late Friday by JYP Entertainment Corp. that quickly went viral, Chou said she felt proud to be Chinese and that there was only one China, fueling suspicion that the agency may have pressured her to apologize to avoid upsetting fans in mainland China, a key market.
